A colleague from a Japanese magazine says that NTT East has offered 100Mbps bi-directional service at Â¥5880 (around Â£30) a month including VAT since April this year.

And NTT West has an even more impressive offering, selling a similar service for Â¥5670. Neither service has any cap for downloading and while customers have to contract for the service, that is only Â¥500 a month.
